1. complete trust or confidence in someone or something.

Science is not something you have faith in. The entire point of science is allowing your beliefs to change when presented with evidence. That's the exact opposite of "complete trust". If anything, the only thing you need to have faith in is in the validity of your own experience - and that's a philosophical dilemma, not a scientific one.

Doing science means knowing we're probably wrong and will learn something new tomorrow - but we're probably at least a little bit right and that will have made our lives better until now.
